Gun Room

The Gun Room at Wentworth Castle is a Grade II* listed building, likely constructed in the mid-18th century, originally intended as a banqueting house or bath house, and later repurposed as a gun room in the 19th century. It was built for the Wentworth Castle estate and features red brick with ashlar sandstone dressings. The building has a modillioned ashlar cornice and a hipped Welsh slate roof, and is a square, single-storey structure.

The main facade includes an ashlar plinth and sill band, with a central projection that features a badly-weathered Doric Venetian window. This window has paired side lights, with the outer lights being blind and one inner light showcasing margin-light glazing. Above the window, there is a frieze adorned with triglyphs and bucrania, and an open pediment that encloses the round-arched head of the central light. On the right side of the building, there is an original doorway with an architrave and pediment to the left, and to the right, a late 19th-century hipped-roof canopy supported by sturdy wooden posts, alongside an old 18-pane sash window.

Inside, the Gun Room retains remnants of fine mid-18th century plasterwork. The entrance features a curved apse with a moulded plaster doorcase decorated with Vitruvian scrolls beneath cornices. There are Corinthian-columned side screens, each with sections of entablature carried over beneath a shallow segmental arch. The octagonal ceiling bosses in the apsidal end bay are decorated with floral designs, and there is a smaller tiled room located at the rear.
